How to choose
Match coverage to your room size
Coverage is the maker's own figure, so compare it with your room's floor area before looking at other features. The DREO Space Heater is at 200 sq ft, the Cozy Products heater at 150 sq ft, and the Teioe and PRSOOY heaters at 100 sq ft each. Pick a heater whose figure covers your room, rather than judging size from the heater's height or width alone.
Thermostat, modes and ECO settings
A thermostat lets a heater hold a set temperature by cycling on and off, while plain heat settings only pick a power level. The DREO Space Heater and the Cozy Products heater have adjustable thermostats. The DREO Space Heater and the TABYIK heater have ECO mode, and the DREO Space Heater has 5 modes while the Teioe heater has 3 modes.
Placement and cord care
Give a heater clear floor space, keep its cord out of walkways, and plug it straight into a wall outlet. The DREO Space Heater has a carry handle and the Teioe heater has a leather handle, so either can be moved between rooms. Keep the area in front of the heater clear.
